*Lime Introduction

Lime is a coordination model and middleware based on the ideas found in
Linda, a shared tuple space model developed at Yale in the 1980s. Lime has
three primary incarnations, each tailored for a specific environment,
ranging from mobile ad hoc networks to sensor networks with base stations or
with actuators.

LIME

Lime (Linda in a Mobile Environment) is a model and middleware supporting
the development of applications that exhibit physical mobility of hosts,
logical mobility of agents, or both. Lime adopts a coordination perspective
inspired by work on the Linda model. The context for computation, represented
in Linda by a globally accessible, persistent tuple space, is refined in Lime
to transient sharing of identically-named tuple spaces carried by individual
mobile units. Tuple spaces are also extended with a notion of location and
programs are given the ability to react to specified states. The resulting
model provides a minimalist set of abstractions that facilitate rapid and
dependable development of mobile applications.

TinyLIME

TinyLIME is a middleware for wireless sensor networks (WSN) that departs
from the traditional WSN setting where sensor data is collected by a central
monitoring station, and enables instead multiple mobile monitoring stations to
access the sensors in their proximity and share the collected data through
wireless links. This intrinsically context-aware setting is demanded by
applications where the sensors are sparse and possibly isolated, and where
on-site, location-dependent data collection is required. An extension of LIME,
TinyLIME makes sensor data available through a tuple space interface,
providing the illusion of shared memory between applications and sensors. Data
aggregation capabilities and a power-savvy architecture complete the
middleware features.

TeenyLIME

TeenyLIME is a tuple space model and
middleware supporting applications where sensing and acting devices
themselves drive the network behavior. In other words, the application
core is not confined to the powerful sinks, rather it is deployed on
the devices embedded within the physical world. Tuple space
operations are used both for data collection as well as to effect
coordination among sensing and acting devices.
